Ocean waters are constantly on the move, traveling far distances in complex currents that regulate Earth's climate and weather patterns. How might climate change impact this critical system? Oceanographer, College of Sciences Dean, and Betsy Middleton and John Clark Sutherland Chair Susan Lozier dives into the data in her TED Talk. Her work suggests that ocean overturning is slowing down as waters gradually warm — and her talk takes us on board the international effort to track these changes and set us on the right course while we still have time.TED
Scientists have been trying to build snakelike, limbless robots for decades. These robots could come in handy in search-and-rescue situations, where they could navigate collapsed buildings to find and assist survivors. Georgia Tech researchers Tianyu Wang, a robotics Ph.D. student, and Christopher Pierce, a postdoctoral scholar in the School of Physics, recently shared how they go about building these robots, drawing inspiration from creatures like worms and snakes. Wang and Pierce work with Daniel Goldman, Dunn Family Professor in the School of Physics.The Conversation
The secret to the evolutionary success of organisms like plats, green algae, and cyanobacteria is light-harvesting proteins that harness energy from the sun. Long before photosynthetic proteins dominated the planet, another group of light-harvesting proteins made their debut: rhodopsins. Now, reporting in Current Biology, a team of evolutionary and synthetic biologists reenacted this process by transferring a rhodopsin gene from one eukaryotic species to another to see whether it still functioned in its unfamiliar host, offering a glimpse into how rhodopsins found their way into eukaryotic evolutionary history. Study authors include biology Ph.D. student Autumn Peterson, Research Scientist Anthony Burnetti, CMDI grant writer Carina Baskett, and Associate Professor William Ratcliff.The Scientist
